Emile Hirsch has those classic young Hollywood looks that teen magazines really go for and he does the day-to-day in Rom-Coms very well, but Emile Hirsch is clearly not content to make life easy for himself as an actor and more power to him.

Taking on a role in a tough film like Killer Joe is a million miles from the safe mainstream. Playing down and dirty in an amoral fable with no definitive heroes will certainly give a performer room to expand their range.

Matthew McConaughey delivers a career-best performance in this violent and darkly comic neo-noir thriller that marks a blistering return to form for “The Exorcist” and “The French Connection” director William Friedkin.

When small-time drug dealer Chris Smith finds himself seriously in debt to his supplier, he hatches a plan to have his estranged mother killed in order to claim the $50,000 life insurance due to be paid to his younger sister, Dottie. To do the job, he hires Killer Joe Cooper, a creepy, corrupt and crazy Dallas cop who Chris is informed moonlights as a professional hit man. Unable to pay Joe’s fee upfront, Chris agrees to provide a “retainer” in the form of Dottie, with whom Joe has immediately become besotted. However, following the murder of his mother, Chris’ plan begins to unravel in a series of unexpected twists involving the interference of his father’s new wife, Sharla, and the development of an unlikely bond between Joe and Dottie.

As pure, unadulterated entertainment Friedkin’s second collaboration with writer Tracy Letts (following 2006’s “Bug”) has it all – steamy sexuality, shocking violence, a compelling storyline, lashings of black humour and, most of all, a killer cast of actors all at the top of their game. McConaughey effectively shakes off his rom-com shackles once and for all, while Juno Temple delivers a scene-stealing performance in a movie likely to leave viewers both exhilarated and shaken at the same time.
